PURPOSE: A device for preventing dewing on evaporator case is provided to prevent dewing on a surface of the evaporator case by forming heat insulating layer containing air space between the evaporator case and an insulation plate. CONSTITUTION: A plurality of protrusions(3) are formed on a surface of an evaporator case(1). An insulation plate(2) is installed on the protrusions to form air spaces(4), insulating heat, between the evaporator case and the insulation plate. The air spaces are formed to be lattice-like, linear or mazy. The insulation plate and the air spaces constitute double heat insulating layers to prevent outside air from directly contacting an evaporator at low temperature.
